9 Claims. (Cl. 154-44)' The, present invention relates to improvements, in insulating bats and more particularly to afolded bat, hereinafter referred to as a "fold-bat,

and to an internal support therefor.

In the use of fold-bats of fibrous material such as glass wool, cotton, mineral or slag wool, balsam'pulp and similar insulating substances, particularly those which generally comprise a fluify body of loosely matted fibers, sheetspf material such as corrugated board have been used as cores.- The use of such a material in the core has several limitations in that it is not heatresistant, and it tends to rot, lose its strength and emit an odor upon becoming damp.

It isan object of the present invention to provide a supporting medium for fold-bats which is moisture and heat-resistant to a high degree and does not weaken with age.

Another object is to provide a support which facilitates handling and installing of fold-bats and which is exceedingly inexpensive in manufacture.

A further object of the present invention is to provide a fold-bat having a support thereineral support at the fold of the bat which prevents the fibrous material from being pulled away from the walls and the cavity into which it is installed, so as to insure substantially complete fill ing of the top of the cavity.

Other objects and advantages of the present invention will become apparent from the following description taken in conjunction with the drawing in which:

Fig. I discloses an elevational view of one of my supports.

Fig. II is an elevational view of a modification thei'eof including a supporting ledge for the fold of the bat.

Fig. is a top planview of the embodiment of Fig. Fig. IV illustrates an elevation view of a further modification.

Figs. V and VI depict-elevational and top plan views respectively of another embodiment.

Figs. VII and VIII. show elevational views of additional modifications.

Fig. IX illustrates a perspective assembly view of a fold-bat having one of my supports mounted therein; and

Fig. I shows a supporting frame or member I formed of a wire which is bent in a trapezoidal form and has its ends joined by means of a weld 2 or the like. laid along the fold 4 of the bat 5 as shown in Fig. IX. The bat 5 may be formed from a blanket of fibrous material such as cotton, glass -wool, balsam pulp or the like, which i folded upon itself so as to form a double layer. G of the frame extends down to and lies flush 10 with the lower edge I of the bat. In this manner the edge 6 may be held by the operator when installing the fold-bat into a receptacle or cavity, such as between the walls of an ice-box, stove, package or the like. It will be noted that in in- 15 stalling; my fold-bat, the folded edge 4 is introduced foremost into a cavity and the bat then is pushed forward by pressure applied through I the supporting frame, the pressure being transmitted to the bat along the edge 3 of the supporting frame without material distortion or lumping of the bat. In this manner it is possible to fill a cavity with fibrous insulating material expeditiously and economically, and with the assurance that the fibrous material is distributed uniformly throughout the cavity to produce optimum insulating qualities.

The upper edge 3 of the frame is The lower edge Owing to the open formationof the supporting frame, thetwo adjacent surfaces 8 of the bat are permitted to lie contiguously, with the fibers which 30 .formsaid surfaces more or less intertwined, so as to hold said surfaces together. 'served that due to the trapezoidal shape of my supporting member, the two sides 9 and Ill have 1. a lateral component which, when the fibrous material is gripped therearound with the bat in an upright position, helps to support the bat in a vertical direction. Moreover, in the particular .embodiment of Fig. I, dueto the fact that end 6 is shorter than end 3, the sloping sides 9 and 40 ll! lie embedded in the fibrous bat and prevent the lower part of the bat from slipping through the frame or past said sides as it would do if the sides were conterminous.

It is to be ob- Fig's. H and III illustrate a modification of the present invention. The supporting member is again formed from a single piece of wire bent to the shape shown and having its ends connected at joint 2,, and has a broad supporting flange or -ledge Ii for engagement with the folded edge 0 4 of the bat. When a bat of loose, flufi'y material is folded over the ledge ll, it is broadened along the ledge or distended laterally so that when the bat is installed in an upright position in a corre- Fig. X is a top view of a modification of a ledge. spondingly shaped cavity, the upper portion of the 55 the upper edge will be prevented from stretching;

. and falling away from the'sides of the cavity.

The lower edge I! of the frame is formed with an upward extending cross-member I! in the shape of a reentrant angle or any other suitable form which may assist in supporting the bat in a vertical direction.

Fig. IV depicts a slight modification of the embodiment of Fig. I in that the corners II are somewhat sharper ,and permit the edge 3 to lie along the full length of the fold 4 ofthe bat.

In Figs. V and VI, I have disclosed a frame I5 having a ledge l6 formed from the same or a separate piece of wire bent into an elongated loop, extending along the upper end of the frame and fastened, thereto by means of welds l1.

Fig. VII illustrates a frame made of a single length of wire which has no joint or weld therein. The free ends 20 extend upward but can also extend in a cross-direction to serve as supports for the bat. Of course, it will be understood that a ledge. such as is shown in Figs. III and/or VI if desired, may be provided with this form of frame.

As another form of ledge, I have provided as ,depicted in Fig. VIII a circuitous wire member 22 extending along the upper edge 3 of the frame. It will be noted that this circuitous member, illustrated in the form of a helix, may be joined to the upper edge of the frame inany suitable manner such as by winding it therearound, weld ing or thelike. In Fig. X a ledge 23 is integral with the lower portion of the support in'that it is formed of a single bent wire. With the zigzag formation of the ledge, a simple, expedient type ledge is provided which inte'rmeshes with and supports the fibers of the fold-bat.

Although I have illustrated and described my invention in connection with specific embodiments thereto, it is to be understood that modifications may be resorted to without departing from its scope and spirit as defined in the appended claims.

I claim: 1. An insulating article of fibrous material which comprises a bat folded over upon-itself to form a double thickness having the free ends of said bat terminating together at one end thereof, and a supporting member therefor embedded between the contiguous surfaces of said bat, said supporting member having a laterally disposed ledge lying along the inner edge of said fold. 2. An insulating article of fibrous material which comprises a bat folded over upon itself to form a double thickness having the free ends of said bat terminating together at one end' thereof, and a supporting member therefor embedded between the contiguous surfaces of said bat, said supporting member having a laterally disposed ledge lying along the inner edge of said fold, and

having one edge of said supporting member lying flush with the free ends of said bat.

3. An insulating article of fibrous material which comprises a bat folded over upon itself to form a double thickness having the free ends of saidbat terminating together at one end thereof, and a supporting member therefor embedded between the contiguous surfaces of said bat, said supporting member being formed of a bent wire and having a laterally disposed ledge lying along the inner edge of said fold.
